Sort A Table Into Ascending Or Descending?
Mar 3, 2011I am currently building a table by retrieving a number and a name from an XML document and dynamically building a table. Currently, the table is built and you can check a box to choose whether or not you want to randomize the numbers that correspond to the name. I need to be able to check another box to determine whether or not you want it ascending or descending order. I don't know how to do sorts on a Table Object. Do I have to read it into an Array first and then re-read them into the table?
XML Document Example:
- <roster>
- <student>

.net - DataGridView Sort Does Not Work
Nov 9, 2010Visual Studio 2010 VB.NET
I have a DataGridView.DataSource set to a Collection of custom objects. The columns use read only properties from the custom object for display, this dialog is for display only. The properties all return String objects. I set the columns all but 2 of them to sortmode automatic (the ones that are not set is a button or a checkbox). Yet it does not sort. I have googled around and most people use sql or binding sources but I am using a trivial vb collection. Some say I should implement IComparable but isn't String already IComparable?
Per a request here are some code snippets.
This method defines the columns in detail from columns I designed in the designer.
The column names are called pSelected or pCustomer and corresponds with a property by the same name that the column definition ties to.

DataGridView Find Out Sort Order
Jun 13, 2010I am using VB.NET 2008 My DataGridView is bound to a DataSet. After adding a DataGridView row (from another form), I needed to sort the DataGridView in order to put the new row in the appropriate place. I needed to be able to identify the current sort column and the current sort direction (ascending/descending) but I was unable to find out how to obtain that information from the DataGridView properties. Consequently I had to do it the hard way via my own coding. The sort column name (or names) and the sort direction then became available to my program in the global variables.

DataGridView Sort Chg Throwing NullExceptionError
Oct 25, 2011I have the below bit of code that allows a user to see data in a DataGridView. They can click on a single row and open another form with the detail of the selected item. Once the user returns from that form I refresh the original screen with anything that might have been changed from the other screen (or by other users elsewhere in the network).
This works perfectly fine to select items, go look a the detail and change anything you like, then return and refresh the screen with the new updated information, with one notable exception. I get a NullExceptionError whenever the user has changed the default datagridview sort option on the first screens grid screen. Then selects and item and goes to the second screen and comes back to the first screen. And the really strange thing (to me) is that the first record on the return gets added fine, it is the second record it tries to add that is throwing the error.
Other notes: all variables have values (not nulls), the tableSelect is also valid and not equal to nothing.

View 7 RepliesIDE :: DataGridView Sort With Total Line?
May 25, 2012I'm moving code from using MSFlexGrid to DataGridView.My programming approach is to leave the total line in the last row of the grid. I prefer not to change this. I successfully handled this with MSFlexGrid by turning off the automatic sort and invoking a manual sort when the header row was clicked. I was able to select the cells I wanted affected by the sort. I selected all cells but the final row and then did MSFlexGrid1.sort. This worked.I have read up on the DataGridView sort. I can make my grids sort and I can turn-off automatic sorting and can force a sort programatically. I have NOT been able to do a sort in a manner that excludes the last row.

Sep 28, 2011I have a datagridview showing data from an Access database. I have dragged the datagridview from "Data Sources" window - and not written any code. In bindingsource I have choose to sort on an autonumber field. Is it possible to let the user use the mouse to change the order, and the database to remember this the next time the user starts the application.I guess I have to have a number field in the database, and write code to change the value in number field as the user change order - and then save this back to the database? Does the datagridview support changing order by mouse at all?
